To all whom it may concern:

Be it known that I, AanoLo S. \Vnnsrcn, Jr.,'citizen of the United States, and resident of Camden, county of Camden, and State of New Jersey, have invented an 1mprovement in Explosive-Engines, of which the following ls a specification.

The object of my invention is to provide explosive engines, more especially employed in automobiles, with auxiliary heating devices, preferably for employing electrical energy as the source of heat, for maintaining the water jacket of the cylinders in a warm condition to prevent freezing of the water therein when the machine is standing and the engine out of operation.

llcretofore much damage has beendone by the cooling water in the jacket of the engine cylinders becoming frozen and the expansion thereof rupturin the jackets or" the cylinders, producing leaxs which are difiicult of repair and mostly requiring 116V cylinders as replacement of the injured members. By use of my invention, this danger is overcome, as a sullicient quantity.

of heat may be radiated from the heater upon the outside of the cylinder jackets to maintain the Water therein above the freezing point; and as the necessity for this precaution only exists in very cold weather and when the automobile is required to stand in the open air for a long period of time, the cost of the heating would only apply to those short periods of use.

My invention consists in surrounding the water jacket portions or cylinders of the explosive engine with an electric or other heater and combining therewith a suitable source of electric or other heat generating energy and controlling means. As this heater is itself inelosed by the hood over the engine, the heat radiated upon the engine cylinders remains confined to a lar 'e extent within the hood, and thereby rm uccs the size of the heater necessary very materially to what would be required it the hood were employed. I also provide the front of the heater with removable or door portions which in cold weather, are/ kept closed but in warm weather said doors are retained open or removed to provide opportunity for the usual air circulating fan driving the cooling air directly upon the engine cylinunderstood by reference to the drawings,

in which z- I Figure 1 is a side elevation of a portion of an automobile embodying my invention and having the front portion of the engine hood cut away; Fig. 2 is a plan view of the same with the engine hood removed; Fig; 3 is a sectional plan view of the electric heaterv removed from the engine, the section being taken on line of Fig. 1 and broken across to shorten its length; and Fig. 4 is vertical cross section through one of the side portions of the electric heater taken on line yy of Fig. 3. is the main frame or chasis of the auto mobile, 3 is the usual cooler, 4c is the engine" hood and 7 is the dash board. The engine 5 is of the explosive type and of any construction which employs water jackets for its cylinders; said engine being provided with a crank case 8. Air may be circulated over the engine cylinders by the usual circulating fan 6. These parts may be of any usual construction.

Surrounding the engine cylinders 5, I' provide an electric heater, consisting of the two side portions 9, 9, having flanged ends 12 by which they may be united into annular Form by the thumb bolts 13, (Fig. This electric heater may rest upon the crank case andbe provided with lugs llthrough which clamping screwslO may pass for firmly securing it to the crank case.

The rear end of the heater may be semi circular, as indicated at 9", but the" forward end is preferably made polygonal in shape,

as at 9, the flattened portions (o -responding lo doors 17 above them, as indicated in Figs.

1 and 2; the purpose of which doors is to more readily control the air passing over the engine in summer and in very cold weather providing means for shutting off excessive draft from the circulating fan 6.

lining 14:. The heating wires are indicatedat 15 and may be wound around upper and lower insulator rods 1610f any suitable construction. In practice, one terminal of the is wires 15 of each half 9 of the heater may be connected to the heater case and thereby be grounded to the engine, the other terminals of;

the wires 15 extending from the case as insulated wires 23 and connecting with a 15 socket 22; said wires 28 may beconnected'in parallel. Current may be supplied from a storage or other battery 26 to the electric heater by the wire 25, having a plug 24 which fits the socket 22 on the dash board 7. 22) The other circuit 27 from the battery is grounded to the engine and in that way is in circuit with the other terminals of heater wires 15. In place of the battery 26, a dynamo or other source of electric energy may be provided, as the source of current is immaterial to my invention. By withdrawing the plug 24, the heater will be out out of action.

The doors 1? are hinged at 18 to the s heater casin parts 9, and when closed, they meet about t e fan shaft and may be secured by thelocking bolt 21 (Fig. '2). When in this position, the main draft of the fan 6 is cutof]? from the engine, and this may be the i case' in very cold weather and especially where the engine is run slowly and not employed continuously for any long period of time. At other times, the doors 17 are swung outward as indicated in dotted lines 40 in Fig. 2, and clamped against stop braces 19 by clamping bolts 20. In this position of adjustment, the fan 6 may force the air freely upon theengine cylinders and the doors guide it directly upon the cylinder; 15 and the heater case insures the air passing over all of the cylinders and escaping upwardly, and thereby eifecting amore thorough cooling.

l have shown my invention in the form most practical of application, but I do not restrict myself to the details, as these will be modified in many ways'to suit the difien cnttypes of engines and automobile framing, as well as to adapt my invention to the particular uses to which it may be put, it

in no way being restricted to use on automobiles. My invention, moreover, is adapted for use by employment of any auxiliary heater surrounding the water jacketed portionsof the cylinuersfor beating them externally'when the engine is out of operation and hence I do not restrict my invention to i the employment of an electric heater, though I prefer the same. W5 Having now described my invention, what theater I claim as new and desire to secure by Let ters Patent, is

1. The combination of an explosive engine having a water jacket, with a heating device arranged about the water jacket of the engine forproviding heat to prevent freezing of the water within the water jacket when the engine is out of operation said heater being made. in detachable parts, clamps for securing said parts together, and means for securing the'heater to the engine.

2. The combination of an engine having a water jacket, with a heater separate from and surrounding the water jacket of the engine said heater being open at the top, one 30 end of the heater provided with movable portions providing access for air thereto,

and a draft fan arranged in front ofthe opening so provided. I
